DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To make the objects, technical schemes and advantages more clearly, the present application may be further described in detail with reference to the accompanying drawings and embodiments.

In order to overcome the drawbacks in the prior art that the end cover may easily fall apart from the sleeve resulted from the smooth surface contact between them, and the glues between them may run out to be dirty and harmful when implementing the gluing process, in the present application, a knurl configuration for avoiding sliding is provided, the knurl protrudes from the surface of the end cover, where the end cover and the sleeve are contacted closely. The end cover may be a nozzle cover that is set on the end adjacent to the atomizer, or a lamp crown that is set on the end adjacent to the battery and on a side of a lamp for imitating the burning of tobacco.

The atomizer component in the application aims at the case in which the end cover is set on the end adjacent to the atomizer. Referring to FIG. 2, an atomizer component is shown.

The atomizer component is used to constitute an electronic cigarette by combining a battery component. The atomizer component comprises an atomizer sleeve 1 and an end cover 10 inserted into one end of the atomizer sleeve 1. In order to make the connection between the end cover 10 and the atomizer sleeve 1 more stable, a knurl configuration for avoiding sliding is provided, the knurl protrudes from a surface of the end cover 10, where the end cover 10 and the atomizer sleeve 1 are contacted closely.

The specific structure of the end cover 10 is shown in FIG. 3A which shows a first embodiment of the atomizer component.

The end cover 10 comprises a body 100 and a joint part 200 that axially extends away from an edge of the body 100. The knurl configuration is defined on the outer surface of the circumferential side wall of the joint part 200.

The knurl configuration comprises several first grooves 11, the first grooves 11 extend from the body 100 towards one end of the joint part 200 and form a first preset angle with respect to the axis of the joint part 200. The several first grooves 11 form a straight knurl configuration or a twill knurl configuration. The first preset angle is an angle between the central axis of the joint part 200 and the projection that a first groove 11 is projected on to any surface that comprises the central axis of the joint part 200.

In the embodiment, the first groove 11 is a curved groove or a rectangular groove. The distances between any two adjacent first grooves 11 are equal or not. The distance between two adjacent first grooves 11 and the maximum width of the cross-section of the first groove 11 can be designed according to practical conditions. The depth of the first groove may range from 0.2 mm to 0.4 mm. Limited by the size of the end cover, the distances between any two adjacent first grooves 11 are not too small. But if the distances are too large, the anti-sliding effect will be reduced. Therefore, based on the size of the end cover, the amount of the first grooves 11 may preferably range from 20 to 100.

In the first embodiment, the first grooves 11 are curved grooves, and preferably a straight knurl configuration is adopted, namely the first preset angle is 0 degree. The widths of the first grooves 11 may preferably be 0.2 mm. Considering the uniformity of the stress and the beauty of the appearance, the distances between any two adjacent first grooves 11 are equal, and the distance between two adjacent first grooves 11 is equal to the maximum width of the cross-section of the first groove 11. Preferably, the amount of the first grooves 11 is 40.

Referring to FIG. 3B, a second embodiment of the atomizer component is shown.

The knurl configuration comprises several first grooves 11 and several second grooves 12. The first grooves 11 extend from the body 100 towards one end of the joint part 200 and form a first preset angle with respect to the axis of the joint part 200. The second grooves 12 extend from the body 100 towards one end of the joint part 200 and form a second preset angle with respect to the first grooves 11. The several first grooves 11 and second grooves 12 are intersected to form a netlike knurl configuration. The first preset angle is an angle between the central axis of the joint part 200 and the projection that a first groove 11 is projected on to any surface that comprises the central axis of the joint part 200, and the second preset angle is an angle between the projection that the first groove 11 is projected on above surface and the projection that a corresponding second groove 12 is projected on to above surface. The first preset angle and the second preset angle are both larger than 0 degree.

The magnitudes, such as the shape, depth, packing density, width, etc., of the second grooves 12 are completely same with, partially same with, or completely different from that of the first grooves 11. Considering the uniformity of the stress and the beauty of the appearance, and based on the size of the end cover in combination with the manufacturing of the knurl configuration, in the embodiment, any pair of a first groove 11 and a second groove 12 are symmetrical with respect to the axis of the joint part 200, wherein in one pair of a first groove 11 and a second groove 12, the first groove 11 and the second groove are intersected with each other. In other words, on any surface that comprises the central axis of the joint part 200, the projection of the first groove 11 and the projection of the second groove 12 are symmetrical with respect to the central axis. The distances between any two adjacent first grooves 11 are equal.

In the second embodiment, the first grooves 11 are rectangular grooves, and preferably a netlike knurl configuration is adopted, namely the first preset angle and the second preset angle are both equal to 30 degree. The widths of the first grooves 11 are equal to that of the second grooves 12, preferably equal to 0.4 mm. Considering that it is more complex to establish grooves in the netlike knurl configuration than in the straight or twill knurl configuration, the distance between two adjacent first grooves 11 is three times of the maximum width of the cross-section of the first groove 11. In this way, the manufacturing process can be reduced, and the protruding area formed from the netlike grooves can be ensured to afford enough friction. Preferably, the amount of the first grooves 11 is 80.

The several first grooves 11 form a straight knurl configuration or a twill knurl configuration. The first preset angle is an angle between the central axis of the joint part 200 and the projection that a first groove 11 is projected on to any surface that comprises the central axis of the joint part 200.

In the embodiment, the first groove 11 is a curved groove or a rectangular groove. The distances between any two adjacent first grooves 11 are equal or not. The distance between two adjacent first grooves 11 and the maximum width of the cross-section of the first groove 11 can be designed according to practical conditions. The depth of the first groove may range from 0.2 mm to 0.4 mm. Limited by the size of the end cover, the distances between any two adjacent first grooves 11 are not too small. But if the distances are too large, the anti-sliding effect will be reduced. Therefore, based on the size of the end cover, the amount of the first grooves 11 may preferably range from 20 to 100.

In the first embodiment, the first grooves 11 are curved grooves, and preferably a straight knurl configuration is adopted, namely the first preset angle is 0 degree. The widths of the first grooves 11 may preferably be 0.2 mm. Considering the uniformity of the stress and the beauty of the appearance, the distances between any two adjacent first grooves 11 are equal, and the distance between two adjacent first grooves 11 is equal to the maximum width of the cross-section of the first groove 11. Preferably, the amount of the first grooves 11 is 40.
